The buzz surrounding the anti-glare search engines is on! With a number of anti-glare search engines like Blackle introducing a new theme of using a black screen for saving energy, people are curious to find out the truth about its claim. According to an article published by Mark Onktush in January, 2007, turning Google page black would save 3000 MWh per year!


Interesting as it sounds, there are actually a number of aspects to be taken into consideration prior to resting a complete belief in the theory of the anti-glare search engines. Mark, in his article, claimed that Google could actually save 750 MW hours a year using a black screen. This, in fact, is true for cathode ray tube (CRT) monitors, which consume more power. The black screen would definitely use around 15 watt less in CRTs. But what about LCD monitor users? To be precise, Mark had himself claimed that around 25% of people use CRT monitors. If such is the case, would a black screen really be a great help for LCD users?


As said earlier, the CRT users would save around 15 watts less energy than their LCD counterparts, amounting to 1,917,750 kWh (511,400,000 hours x 25% x .015 kW). This is definitely good news for CRT users. However, there is a flip side to it as well. The LCD users can hardly benefit from a black screen for they use a black lit display, selectively blocking out certain wavelengths of light. It is surprising to find that an LCD monitor actually consumes an extra watt when switched on to black screen. However, the CRT users would definitely be benefited by setting up anti-glare screen as their home page.


The concept of anti-glare search engines or Black Google has been criticized widely. But it would not be altogether correct to negate the whole issue by claiming it as worthless. People should appreciate the fact that importance is being placed on health issues of the users. Anti-glare screens are easy to read as they negate straining of the eyes. Energy saving or not, users certainly feel easier to read on a black screen than their colored counterparts. The debate on anti-glare search engine has gained from strength to strength. In spite of multiple criticisms, we sincerely believe that the concept should really be worked upon and bettered.
